Do not "start up automatically after a power failure."
Early this morning, the power went off in my house for several minutes. I have a 2017 iMac running Ventura, 13.7. I also have the first Mac mini using the M1 chip. A few days ago I upgraded it to the new Sequoia Mac OS. The Mac mini is my future replacement. I got it a couple years ago when I thought my iMac Fusion drive had died. It turned out that there was a restore procedure that brought it back to life. Anyway, both of them were in sleep mode when the power went out. I never select, "start up automatically after a power failure." Nevertheless, both of them booted up again when the power came back on. My cursory search found nothing about this issue. I've gone through all my settings carefully. I could not find anything that might override my choice.
Has anyone else had this problem? Does anyone have a solution for this problem? I don't like having to reboot my computers on a daily basis. I normally shut them down once a week, unless I had to restart them for some other reason. And the iMac is in my bedroom. When that screen comes on in the dark, it's like having a sunrise in your bedroom. Very annoying and disruptive.
